[oe] [meta-oe][PATCH] catch2: new package

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bgolaszewski at baylibre.com>

Add a recipe for the catch2 testing framework. There's a bug upstream
which makes it impossible to build with gcc7 so include a patch.

+Subject: [PATCH] internal: fix build in GCC 7
+
+The following error is emitted by gcc 7:
+
+include/internal/catch_tostring.cpp:217:21: error: comparison is always true due to limited range of data type [-Werror=type-limits]
+|      } else if ('\0' <= value && value < ' ') {
+|                 ~~~~~^~~~~~~~
+| cc1plus: all warnings being treated as errors
+
+We can drop the first part of the if.
